REFRIGERATOR CONSTRUCTION.

Application filed January 17, 1924. Serial No. 886,882.

casting stone onto fibrous material has been described in my previousapplication Serial No. 681,901, and need not be here described indetail. Means are provided however for mechanically uniting the caststone shell to the wooden front so as to form a complete unit of theouter shell comprising a wooden front with a cast stone side, top andbottom walls. One advantage of using a wooden front is that the innershell which partitions off the ice chamber and food chamber from therest of the refrigerator may be abutted against the wooden front,thereby insualting the ice chamber and food chamber from the exteriorwalls of the outer shell. As is well known, wood is a very good heatinsulating material and in cast stone refrigerators of this character,it is necessary that the interior be thoroughly insulated from theexterior as stone is a very good conductor of heat.

Another advantage of the wooden front is to provide a more suitablemedium to support the hardware and fittings.

Still another advantage is that the wooden front is better suited towithstand the shocks incident to the slamming of the doors.

In the drawings:

Fig. l is a front elevation of a refrigerator constructed in accordancewith my invention.

Fig. 2 is a horizontal sect-ion taken on the line 2-2 of Fig. 4.

Fig. 3 is a vertical section taken on the line 3-3 of Fig. 2.

Fig. 4 is a section taken on the line 4- l of Fig. 3.

Fig. 5 is a fragmentary perspective View of one corner of therefrigerator front, showing the reinforcing angles secured thereto.

The refrigerator comprises the cast stone outer shell a and the caststone inner shell Z). The entire front 0 of the refrigerator is of woodand provided with suitable door openings so that access may be had tothe ice chamber and the food compartments. Secured to the back side ofthis wooden front 0 are perforated angle irons (Z. These angles arelocated about the four sides of the front and the outer shell is castdirectly onto the wooden front, the cement flowing around the angleirons and passing through the holes 6 in the upright web of the angleirons.

Since these angle irons are permanently secured to the front by means ofscrews or other fastening devices, the stonework of the outer shell iscast directly onto the wooden front and this forms a unit constructionof the outer shell which comprises a wood front and cast stone top,bottom and side walls.

The refrigerator here illustrated is commonly known as a sideicer. Theinner shell which divides the ice chamber from the food compartments is.substantially L shaped, and is shown distinctly in 4. This inner shellis assembledto the open back of the outer shell and abuts the Woodenfront of the refrigerator. The angles 10, are secured to the woodenfront and this inner shell is fitted therein so that the front of thesaid inner shell will rest on the horizontal angle and is held againstsidewise movement by the vertical angles. The back plate f is fittedinto the opening in the back of the outer shell, and the inner shell isprovided with a plurality of bosses g in which are anchored the'tappedbushings k; screws 2' pass through this sheet metal back 7" and into thetapped bushings for holding the inner shell in place within the outershell. Suitable insulating material j is rammed in between the inner andouter shells and around the ice chamber for further insulating theinterior of the refrigerator from the outside atmosphere.

A perforated fiber sheet is cast within the stonework and serves toreinforce the same. This construction of course is similar applicationSerial No. 653,090 and need not be described here. The ice chamber m isof usual construction and in fact, the general shape and arrangement ofmy refrigerator may be varied without departing from the spirit of myinvention, whichis to cast an outer shell of stonework onto a woodenfront and to telescope the inner shell within the outer shell, the woodfront serving to insulate the two shells.

hat I claim is:

1. A refrigerator, in which the outer Shell to the constructiondescribed in my previous V of another material having a reinforcementreinforcement and the remainder of the shell is a solid cast stoneworkand the front is mechanically united theretoand cast into the stonework.r

2. A refrigerator, in which the front is a wooden member having aperforated angle isofstonework cast onto such reinforcement.

3. A refrigerator, having the. outer shell constructed of stonework witha wooden front united thereto; and an inner shell of stoneworkelescopical y" suppor e w spect to the outer shell and abut-ting upVagainstthe wooden front of the refrigerator.

' 4i. A refrigerator, having an outer shell of reinforced.stoneworkunited with a front of material having a low heat conductivity, and aninner shell supported in spaced relation with respect to the stoneworkouter shell by abutting against the Wooden front.

In testimony whereof I have affixed my signature.
